Deploying Overcloud with L3 routed networking
|
||||
=============================================
|
||||
|
||||
Layer 3 Routed spine and leaf architectures is gaining in popularity due to the
|
||||
benefits, such as high-performance, increased scalability and reduced failure
|
||||
domains.
|
||||
|
||||
The below diagram is an example L3 routed
|
||||
`Clos <https://en.wikipedia.org/wiki/Clos_network>`_ architecture. In this
|
||||
example each server is connected to top-of-rack leaf switches. Each leaf switch
|
||||
is attached to each spine switch. Within each rack, all servers share a layer 2
|
||||
domain. The layer 2 network segments are local to the rack. Layer 3 routing via
|
||||
the spine switches permits East-West traffic between the racks:
|
||||
|
||||
.. image:: ../_images/spine_and_leaf.svg
|
||||
|
||||
.. Note:: Typically Dynamic Routing is implemented in such an architecture.
|
||||
Often also
|
||||
`ECMP <https://en.wikipedia.org/wiki/Equal-cost_multi-path_routing>`_
|
||||
(Equal-cost multi-path routing) and
|
||||
`BFD <https://en.wikipedia.org/wiki/Bidirectional_Forwarding_Detection>`_
|
||||
(Bidirectional Forwarding Detection) are used to provide non-blocking
|
||||
forwarding and fast convergence times in case of failures.
|
||||
Configuration of the underlying network architecture is not in the
|
||||
scope of this document.
|
||||
|
||||
Layer 3 routed Requirements
|
||||
---------------------------
|
||||
|
||||
For TripleO to deploy the ``overcloud`` on a network with a layer 3 routed
|
||||
architecture the following requirements must be met:
|
||||
|
||||
* **Layer 3 routing**:
|
||||
The network infrastructure must have *routing* configured to enable traffic
|
||||
between the different layer 2 segments. This can be statically or dynamically
|
||||
configured.
|
||||
|
||||
* **DHCP-Relay**:
|
||||
Each layer 2 segment that is not local to the ``undercloud`` must provide
|
||||
*dhcp-relay*. DHCP requests must be forwarded to the Undercloud on the
|
||||
provisioning network segment where the ``undercloud`` is connected.
|
||||
|
||||
.. Note:: The ``undercloud`` uses two DHCP servers. One for baremetal node
|
||||
introspection, and another for deploying overcloud nodes.
|
||||
|
||||
Make sure to read `DHCP relay configuration`_ to understand the
|
||||
requirements when configuring *dhcp-relay*.
|
||||
|
||||
Layer 3 routed Limitations
|
||||
--------------------------
|
||||
|
||||
* Some roles, such as the Controller role, use virtual IP addresses and
|
||||
clustering. The mechanism behind this functionality requires layer-2 network
|
||||
connectivity between these nodes. These nodes must all be placed within the
|
||||
same leaf.
|
||||
|
||||
* Similar restrictions apply to networker nodes. The Network service implements
|
||||
highly-available default paths in the network using Virtual Router Redundancy
|
||||
Protocol (VRRP). Since VRRP uses a virtual router ip address, master and
|
||||
backup nodes must be connected to the same L2 network segment.
|
||||
|
||||
* When using tenant or provider networks with VLAN segmentation, the particular
|
||||
VLANs used must be shared between all networker and compute nodes.
|
||||
|
||||
.. Note:: It is possible to configure the Network service with multiple sets
|
||||
of networker nodes. Each set would share routes for their networks,
|
||||
and VRRP would be used within each set of networker nodes to
|
||||
provide highly-available default paths. In such configuration all
|
||||
networker nodes sharing networks must be on the same L2 network
|
||||
segment.
|
||||
|
||||
Create undercloud configuration
|
||||
-------------------------------
|
||||
|
||||
To deploy the ``overcloud`` on a L3 routed architecture the ``undercloud``
|
||||
needs to be configured with multiple neutron network segments and subnets on
|
||||
the ``ctlplane`` network.
|
||||
|
||||
#. In the ``[DEFAULT]`` section of ``undercloud.conf`` enable the routed
|
||||
networks feature by setting ``enable_routed_networks`` to ``true``. For
|
||||
example::
|
||||
|
||||
enable_routed_networks = true
|
||||
|
||||
#. In the ``[DEFAULT]`` section of ``undercloud.conf`` add a comma separated
|
||||
list of control plane subnets. Define one subnet for each layer 2 segment in
|
||||
the routed spine and leaf. For example::
|
||||
|
||||
subnets = leaf0,leaf1,leaf2
|
||||
|
||||
#. In the ``[DEFAULT]`` section of ``undercloud.conf`` specify the subnet that
|
||||
is associated with the physical layer 2 segment that is *local* to the
|
||||
``undercloud``. For example::
|
||||
|
||||
local_subnet = leaf0
|
||||
|
||||
#. For each of the control plane subnets specified in ``[DEFAULT]\subnets``
|
||||
add an additional section in ``undercloud.conf``, for example::
|
||||
|
||||
[leaf0]
|
||||
cidr = 192.168.10.0/24
|
||||
dhcp_start = 192.168.10.10
|
||||
dhcp_end = 192.168.10.90
|
||||
inspection_iprange = 192.168.10.100,192.168.10.190
|
||||
gateway = 192.168.10.1
|
||||
masquerade = False
|
||||
|
||||
[leaf1]
|
||||
cidr = 192.168.11.0/24
|
||||
dhcp_start = 192.168.11.10
|
||||
dhcp_end = 192.168.11.90
|
||||
inspection_iprange = 192.168.11.100,192.168.11.190
|
||||
gateway = 192.168.11.1
|
||||
masquerade = False
|
||||
|
||||
[leaf2]
|
||||
cidr = 192.168.12.0/24
|
||||
dhcp_start = 192.168.12.10
|
||||
dhcp_end = 192.168.12.90
|
||||
inspection_iprange = 192.168.12.100,192.168.12.190
|
||||
gateway = 192.168.12.1
|
||||
masquerade = False
|
||||
|
||||
Install the undercloud
|
||||
----------------------
|
||||
|
||||
Once the ``undercloud.conf`` is updated with the desired configuration, install
|
||||
the undercloud by running the following command::
|
||||
|
||||
openstack undercloud install
|
||||
|
||||
Once the ``undercloud`` is installed complete the post-install tasks such as
|
||||
uploading images and registering baremetal nodes. (For addition details
|
||||
regarding the post-install tasks, see

DHCP relay configuration
|
||||
------------------------
|
||||
|
||||
The TripleO Undercloud uses two DHCP servers on the provisioning network, one
|
||||
for ``introspection`` and another one for ``provisioning``. When configuring
|
||||
*dhcp-relay* make sure that DHCP requests are forwarded to both DHCP servers on
|
||||
the Undercloud.
|
||||
|
||||
For devices that support it, UDP *broadcast* can be used to relay DHCP requests
|
||||
to the L2 network segment where the Undercloud provisioning network is
|
||||
connected. Alternatively UDP *unicast* can be can be used, in this case DHCP
|
||||
requests are relayed to specific ip addresses.
|
||||
|
||||
.. Note:: Configuration of *dhcp-relay* on specific devices types is beyond the
|
||||
scope of this document. As a reference
|
||||
`DHCP relay configuration (Example)`_ using the implementation in
|
||||
`ISC DHCP software <https://www.isc.org/downloads/dhcp/>`_ is
|
||||
available below. (Please refer to manual page
|
||||
`dhcrelay(8) <https://linux.die.net/man/8/dhcrelay>`_ for further
|
||||
details on how to use this implementation.)
|
||||
|
||||
|
||||
Broadcast DHCP relay
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
DHCP requests are relayed onto the L2 network segment where the DHCP server(s)
|
||||
reside using UDP *broadcast* traffic. All devices on the network segment will
|
||||
receive the broadcast traffic. When using UDP *broadcast* both DHCP servers on
|
||||
the Undercloud will receive the relayed DHCP request.
|
||||
|
||||
Depending on implementation this is typically configured by specifying either
|
||||
*interface* or *ip network address*:
|
||||
|
||||
* **Interface**:
|
||||
Specifying an interface connected to the L2 network segment where the DHCP
|
||||
requests will be relayed.
|
||||
* **IP network address**:
|
||||
Specifying the network address of the IP network where the DHCP request will
|
||||
be relayed.
|
||||
|
||||
Unicast DHCP relay
|
||||
~~~~~~~~~~~~~~~~~~
|
||||
|
||||
DHCP requests are relayed to specific DHCP servers using UDP *unicast* traffic.
|
||||
When using UDP *unicast* the device configured to provide *dhcp-relay* must be
|
||||
configured to relay DHCP requests to both the IP address assigned to the
|
||||
interface used for *introspection* on the Undercloud and the IP address of the
|
||||
network namespace created by the Network service to host the DHCP service for
|
||||
the ``ctlplane`` network.
|
||||
|
||||
The interface used for *introspection* is the one defined as
|
||||
``inspection_interface`` in ``undercloud.conf``.
|
||||
|
||||
.. Note:: It is common to use the ``br-ctlplane`` interface for introspection,
|
||||
the IP address defined as ``local_ip`` in ``undercloud.conf`` will be
|
||||
on the ``br-ctlplane`` interface.
|
||||
|
||||
The IP address allocated to the neutron DHCP namespace will typically be the
|
||||
first address available in the IP range configured for the ``local_subnet`` in
|
||||
``undercloud.conf``. (The first address in the IP range is the one defined as
|
||||
``dhcp_start`` in the configuration.) For example: ``172.20.0.10`` would be the
|
||||
IP address when the following configuration is used::
|
||||
|
||||
[DEFAULT]
|
||||
local_subnet = leaf0
|
||||
subnets = leaf0,leaf1,leaf2
|
||||
|
||||
[leaf0]
|
||||
cidr = 172.20.0.0/26
|
||||
dhcp_start = 172.20.0.10
|
||||
dhcp_end = 172.20.0.19
|
||||
inspection_iprange = 172.20.0.20,172.20.0.29
|
||||
gateway = 172.20.0.62
|
||||
masquerade = False
|
||||
|
||||
.. Warning:: The IP address for the DHCP namespace is automatically allocated,
|
||||
it will in most cases be the first address in the IP range, but
|
||||
do make sure to verify that this is the case by running the
|
||||
following commands on the Undercloud::
|
||||
|
||||
$ openstack port list --device-owner network:dhcp -c "Fixed IP Addresses"
|
||||
+----------------------------------------------------------------------------+
|
||||
| Fixed IP Addresses |
|
||||
+----------------------------------------------------------------------------+
|
||||
| ip_address='172.20.0.10', subnet_id='7526fbe3-f52a-4b39-a828-ec59f4ed12b2' |
|
||||
+----------------------------------------------------------------------------+
|
||||
$ openstack subnet show 7526fbe3-f52a-4b39-a828-ec59f4ed12b2 -c name
|
||||
+-------+--------+
|
||||
| Field | Value |
|
||||
+-------+--------+
|
||||
| name | leaf0 |
|
||||
+-------+--------+
|
||||
|
||||
DHCP relay configuration (Example)
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
In the following example ``dhcrelay`` from
|
||||
`ISC DHCP software <https://www.isc.org/downloads/dhcp/>`_ is started using
|
||||
configuration parameters to relay incoming DHCP request on interfaces:
|
||||
``eth1``, ``eth2`` and ``eth3``. The undercloud DHCP servers are on the network
|
||||
segment connected to the ``eth0`` interface. The DHCP server used for
|
||||
``introspection`` is listening on ip address: ``172.20.0.1`` and the DHCP
|
||||
server used for ``provisioning`` is listening on ip address: ``172.20.0.10``::
|
||||
|
||||
dhcrelay -d --no-pid 172.20.0.10 172.20.0.1 \
|
||||
-iu eth0 -id eth1 -id eth2 -id eth3
|
||||
|
||||
Map bare metal node ports to control plane network segments
|
||||
-----------------------------------------------------------
|
||||
|
||||
To enable deployment onto a L3 routed network the baremetal ports must have
|
||||
its ``physical_network`` field configured. Each baremetal port is associated
|
||||
with a baremetal node in the Bare Metal service. The physical network names are
|
||||
the ones used in the ``subnets`` option in the undercloud configuration.
|
||||
|
||||
.. Note:: The physical network name of the subnet specified as ``local_subnet``
|
||||
in ``undercloud.conf`` is special. It is **always** named
|
||||
``ctlplane``.
|
||||
|
||||
#. Make sure the baremetal nodes are in one of the following states: *enroll*,
|
||||
or *manageable*. If the baremetal node is not in one of these states the
|
||||
command used to set the ``physical_network`` property on the baremetal port
|
||||
will fail. (For additional details regarding node states see
|
||||
:doc:`../advanced_deployment/node_states`.)
|
||||
|
||||
To set all nodes to ``manageable`` state run the following command::
|
||||
|
||||
for node in $(openstack baremetal node list -f value -c Name); do \
|
||||
openstack baremetal node manage $node --wait; done
|
||||
|
||||
#. Use ``openstack baremetal port list --node <node-uuid>`` command to find out
|
||||
which baremetal ports are associated with which baremetal node. Then set the
|
||||
``physical-network`` for the ports.
|
||||
|
||||
In the example below three subnets where defined in the configuration,
|
||||
*leaf0*, *leaf1* and *leaf2*. Notice that the ``local_subnet`` is ``leaf0``,
|
||||
since the physical network for the ``local_subnet`` is always ``ctlplane``
|
||||
the baremetal port connected to ``leaf0`` use ``ctlplane``. The remaining
|
||||
ports use the ``leafX`` names::
|
||||
|
||||
openstack baremetal port set --physical-network ctlplane <port-uuid>
|
||||
|
||||
openstack baremetal port set --physical-network leaf1 <port-uuid>
|
||||
openstack baremetal port set --physical-network leaf2 <port-uuid>
|
||||
openstack baremetal port set --physical-network leaf2 <port-uuid>
|
||||
|
||||
#. Make sure the nodes are in ``available`` state before deploying the
|
||||
overcloud::
|
||||
|
||||
openstack overcloud node provide --all-manageable
|
||||
|
||||
Create roles specific to each leaf (layer 2 segment)
|
||||
----------------------------------------------------
|
||||
|
||||
To aid in scheduling and to allow override of leaf specific parameters in
|
||||
``tripleo-heat-templates`` create new roles for each l2 leaf. The following is
|
||||
an example with one controller role, and two compute roles. Please refer to
|
||||
:doc:`custom_roles` for details on configuring custom roles.
|
||||
|
||||

Configure node placement
|
||||
------------------------
|
||||
|
||||
Use node placement to map the baremetal nodes to roles, with each role using a
|
||||
different set of local layer 2 segments. Please refer to :doc:`node_placement`
|
||||
for details on how to configure node placement.
|
||||
|
||||
Add configuration to parameters_default
|
||||
---------------------------------------
|
||||
|
||||
Before deploying the ``overcloud`` create an environment file that contains the
|
||||
required overrides. In the example below parameter overrides for the following
|
||||
four roles and ``Controller``, ``ComputeLeaf0``, ``ComputeLeaf1`` and
|
||||
``ComputeLeaf2``.
|
||||
|
||||
.. Note:: In TripleO templates role specific parameters are defined using
|
||||
variables. One of the variables used is ``{{role.name}}``. The
|
||||
templates have parameters such as ``{{role.name}}Count``,
|
||||
``{{role.name}}Flavor``, ``{{role.name}}ControlPlaneSubnet`` and
|
||||
many more. This enables per-role values for these parameters, like in
|
||||
the example below where they are used to specify the
|
||||
*ControlPlaneSubnet* node *Count* and *Flavor* to use for the
|
||||
*per-leaf* roles.
|
||||
|
||||
Parameter override example::
|
||||
|
||||
parameter_defaults:
|
||||
ControlPlaneSubnet: leaf0
|
||||
OvercloudComputeLeaf0Flavor: compute-leaf0
|
||||
OvercloudComputeLeaf1Flavor: compute-leaf1
|
||||
OvercloudComputeLeaf2Flavor: compute-leaf2
|
||||
ControllerCount: 3
|
||||
ComputeLeaf0Count: 5
|
||||
ComputeLeaf1Count: 5
|
||||
ComputeLeaf2Count: 5
|
||||
ControllerControlPlaneSubnet: leaf0
|
||||
ComputeLeaf0ControlPlaneSubnet: leaf0
|
||||
ComputeLeaf1ControlPlaneSubnet: leaf1
|
||||
ComputeLeaf2ControlPlaneSubnet: leaf2
|

Deploy the overcloud
|
||||
--------------------
|
||||
|
||||
To deploy the overcloud, run the ``openstack overcloud deploy`` specifying the
|
||||
roles data file and environment file. For example::
|
||||
|
||||
openstack overcloud deploy --templates \
|
||||
-r /home/stack/roles_data.yaml \
|
||||
-e /home/stack/environments/node_data.yaml
|
||||
|
||||
.. Note:: Remember to include other environment files that you might want for
|
||||
configuration of the overcloud.
